What flagword best describes a significant incident to a warhead/bomb that requires Department of Energy recertification?

The term "Bent Spear" accurately describes a significant incident involving a nuclear weapon that necessitates recertification by the Department of Energy. This terminology is specifically used in the context of nuclear surety to refer to incidents where a nuclear weapon is involved in an accidental event or mishap that could compromise its safety or security. A "Bent Spear" incident may include situations such as a transportation accident or a mishandling that impacts the condition and integrity of the warhead. The recertification process ensures that all safety and security measures are re-evaluated and confirmed to be in compliance with established standards.

The other terms, while they relate to different categories of nuclear incidents, do not pertain to the specific need for recertification following a significant incident like "Bent Spear." For example, "Bent Sphere" generally refers to incidents involving the loss of nuclear material but does not imply the need for recertification of the warhead itself. "Bent Shield" and "Bent Signal" are also distinct terms that describe other situations, such as those involving security procedures or communication failures, rather than direct impacts on weapon integrity that necessitate detailed recertification processes.
